WHEELED SCRAPER.

Specification of Letters Patent.

Patented Aug. 18, 191 .1.

Application filed June 26, 1913. Serial No. 775,003.

To all whom it may concern:

Be it known that I, JOHN EDGAR STEELE, a citizen of the United States,residing at Terra Bella, in the county of Tulare and State ofCalifornia, have invented certain new and useful Improvements in VheeledScrapers; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in wheeled scrapers.

One object of the invention is to provide a wheeled scraper which isdesigned particularly for forming banks or checks for irrigatingditches.

Another ob ect is to-provide a machine of this character having meanswhereby the scraping scoop may be readily supported in position forforming banks or ditches, and which is provided with means wherebyeither side of the machine may be raised or lowered, thus enabling thescraping scoop to cut and scrape deeper on one side than on the other.

In the accompanying drawings: Figure 1 is a side view showing the scooparranged for forming checks or ditch banks; Fig. 2 is a top plan viewthereof; Fig. 3 is a vertical cross section of the machine taken on theline 55 of Fig. 1; Fig. 4 is a detail perspective view of the scrapingscoop as arranged for leveling purposes; Fig. 5 is a similar view of thescoop when arranged for forming ditch banks; Fig. 6 is a detailperspective view of the standard for supporting the front end of thescoop when arranged for forming banks; Fig. 7 is a similar view of thestandard for supporting the opposite end of the scoop.

In the embodiment of the invention, I provide a supporting framecomprising parallel side bars 1 and intermediate bars 2 which areconnected at their forward ends by a front cross bar 3 and near theirrear ends by a pair of parallel angle iron cross bars 4 and 5 which arespaced a suitable distance apart and are extended a considerabledistance beyond the side bars 1 as shown. Revolubly mounted in suitablehearings on the side bars and front cross bar are crank axles 6 to theinner ends of which are rigidly connected axle adjusting levers 7 andrevolubly mounted on the outer cranked ends of the axles are supportingwheels 8. By

means of the levers 7 the axles 6 may be rocked in their bearings thusswinging the cranked ends thereof upwardly or down wardly therebyraising and lowering one or both-sides of the machine as will be readilyunderstood. The levers 7 are provided with spring projected pawls 9which are adapted to engage the teeth of segmental racks 10 whereby theaxles are locked in their adjusted positions for supporting the machineat the desired elevation.

The intermediate longitudinal bars 2 are extended beyond the ends of theside bars and have their outer ends connected by a rear cross bar 11.Secured to the rear ends of the bars 2 are short upwardly projectingposts 12 to which are pivotally connected the forward ends of an upperyoke 13, a similar yoke 14 having its ends fixed to a rock shaft 15which is journaled in the ends of the bars 2 as shown. The rear ends ofthe yokes are pivotally connected to the upper and lower ends of abearing sleeve 16 in which is revolubly mounted a caster wheel standard17. On the lower end of the standard 17 is an offset head 18 to which isconnected a fork 19 in which is revolubly mounted a caster wheel 20which supports the rear end of the machine.

Fixed on one end of the rock shaft 15 is an upwardly projecting handlever 21 which is disposed within convenient reach of the drivers seat22 secured to the upper end of the sleeve 16. The lever 21 is providedwith a spring projected pawl 23 which is adapted to engage the teeth ofthe segmental rack 24 whereby the lever is locked in its adjustedpositions. By means of the lever 21 the shaft 15 may be rocked and thesleeve '16, caster wheel standard and the caster wheel connected theretomay be raised or lowered thereby supporting the rear end of the machineat the desired elevation.

Carried by the frame of the machine is a scraping scoop 25 which ispreferably construoted from a curved metal plate having secured to itslower edge a sharp steel cutting and scraping blade 26. This scoop is tobe employed for forming checks or banks for irrigating ditches, trenchesand the like, the same is arranged at an angle across the frame as shownin Figs. 1 and 2 of the drawings. The scoop is supported and attached tothe frame of the machine at its forward end by a standard 32 comprisinga curved scoop engaging lower portion 33 and a rearwardly extendingsubstantially horizontal upper portion 34-. The rearwardly projectingupper portion 3 10f the standard passes over the front cross bar 3 ofthe supporting frame and has its rear end flattened and bolted beneaththe front angle iron cross bar at. The lower curved portion 33 of thestandard is detachably secured to the rear side of the scoop near theupper edge there of by substantially U-shaped clips 35 and at its lowerend said curved portion of the standard is bolted to the scoop as shown.The rear end of the scoop is detachably secured to the frame of themachine by a curved standard 36 which is secured at its forward end tothe under side of the front angle iron cross bar t by a boltor similarfastening. The upper portion of the standard is also detachably securedto the lower side of the angle iron cross bar 5-by a clip, and thecurved lower portion 36 is detachably secured. to the scoop by the clip30 and a bolt 31. The standard 36 has its upper extremity detachablysecured by a clip, to the lower side of the angular cross bar 5, and itslower curved portion detachably secured to the scoop 25 by the clips 30.

The machine is provided with a draft tongue or pole 39 to the rear endof which is secured a cross bar 4E0 the ends of which are connected toangle iron draft bars 41. The forward ends of the bars 41 are secured tothe opposite sides of the pole and the rear,

ends thereof are adapted to be detachably and adjustably connected tothe front cross bar 3 of the frame by hooks or other fastening deviceswhich are engaged with a series of apertures formed in said bar 3. Bythus attaching the pole to the front cross bar of the frame or to oneside of the center of the machine as clearly shown in Fig. 2 of thedrawings, I overcome any side draft which may be caused by the diagonalarrangement of the scoop. I

By providing a scraping scoop and means for detachably securing the sameobliquely to the frame of the machine as herein shown and described, itwill be seen that the dirt when scooped up is continuously dischargedfrom one end of the scoop thus forming the bank. By providing thecranked axle for the front supporting wheels of the machine it will beseen that one or both sides of the front end thereof may be lowered to agreater or less extent to cause the scoop to cut more or less deeply andthat by lowering the machine on one side and raising the same on theother the scoop will be caused Having thus described my invention, whatI claim is:

The herein described scraper comprising a wheeled frame including crossbars, a scoop disposed obliquely across and beneath said frame, astandard having a curved rear portion secured behind the rear end of thescoop and a horizontal upper portion secured to one of said cross bars,and a second standard having a curved forward portion secured behind theforward end of the scoop and a horizontal upper portion extending fromits curved portion rearwardly and passing over one of said frame barsand secured to it and to another frame bar.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOHN EDGAR STEELE.
